Recently, all of the extensions were moved to a new extension: namespace. It appears that this messed up special:search, so now searches will turn up pages of links to nonexistent pages, with no mention of where the content went.
Apparently, these indices aren't being updated on any of the projects; possibly a cron job is down. *** This bug has been marked as a duplicate of 8317 ***
Updating the special pages means running "maintenance/updateSpecialPages.php" and updating the table "querycache". It is *not* related to the search index, which means running the script "maintenance/updateSearchIndex.php" and updating the table "searchindex".
The search index rebuild job for everything but enwiki was stuck and broken. I've unstuck it; seems to be continuing now; should reach mediawikiwiki at some point in the next day or two.
